Best way to determine the ball-to-powder ratio in ball-milling?

To really choose, I guess it depends on the material and your mill (vial, RPM, media, filling volume). I.e. Si80Ge20 is easily alloyed in the high energy SPEX mill. But thermoelectric materials like skutterudites with a peritectic decomposition don't do so well in the SPEX. They can be contaminated by the harden steel vial, and...

In the ball mill refiner the feed material is comminuted between the grinding media, the stirrer and the cylinder wall by compression and shear (Alamprese et al., 2007; Zarić et al.,. 2011). The main factors affecting the grinding action of the ball mill are speed of mill, refining time and quantity, type and size of grinding media.
